Passive Multiplexers, OADMs and Couplers
For the combination (multiplex) and separation (demultiplexing) of optical channels with different wavelengths we offer a myriad of passive components. These can be interpreted in the form of an insertion module for an integrated application within the 10G platform or as an external 19" unit. Multiplexers and demultiplexers are available in versions with 2, 4, 8, 10, 32, 40 or 80 channels. Upon request, they can use one or two optional upgrade ports, which enable MUX / DeMUX units to combine with each other. A major advantage of the upgrade ports is that the development can take place during an ongoing data transmission. At the interconnection of multiple sites, it is possible that not all the optical channels are needed in each location. In order to split off the intermediate points along the fibre optic lines into individual channels, MICROSENS offers a range of Optical Add/Drop Multiplexers (OADMs). By selection, 1, 2, 4 or 8 wavelengths may be added (dropped) or be coupled (added) while all the other optical channels will be transmitted further. The add/drop function can be realized in one direction (unidirectional) or in both directions (bidirectional). Other available passive components are optical couplers. With these devices a transmit channel (TX) can be summarized with a receive channel (RX) on one single fibre (simplex). Thus, it is possible for a bi-directional service such as 10 Gigabit Ethernet or STM-64 to transfer on one single simplex fibre.
